I've given my girlfriend a Papyre 5.1 (Hanlin v5 clone, 5" inch screen) as a Christmas present. She says the the ebook hangs when seeing some JPGs, and she had to reset it two times in a row.

I own a Hanlin V3 since November 2008, and using an old Openinkpot fw, it runs like a charm. Ultra fast, no hangs or strange resets. Overall, very pleased with this fw version. Less options, but rock solid. The problem is that it can't be used on the 5" new Hanlins.

I'd like to know which is the best and more stable V5 firmware out there in your opinion.
